HYDROCAli-BON ROCK-DRILL.

Application filed March 24, 1904, Serial No.

To all whom it may concern: I

Be it known that 1, JOHN V; Rlon', Jr., a citizen of the United. States of America, and Burlington endstetecf New Jersey, have invented certain newnnd usefullmprove: men-ts in Hydrocarbon Rock-Drills, of which the following'is cs ecificetion..

My invention rest-es to an improvement a. resident of Bordentown, in the county of.

in v and itspoh'sctis economicsi-"arrangement of the operating parts are so disposed with ree piston of theengine properthat former, while the operator is relieved of the danger which these ports entail when ex posed.

.The invention further consists in the novel construction, srrsn ement snd cornblnetlon of parts, substantially as will behereinefter .cf the some. suitable clutch like ports in thcvcrious moz'efully described and claimed.

In the annexed drswings illustrating my invention and forming a part of this specificstion, like reference characters refer to fignresand: Figure 1 represents a side elevation of my improved rock drill. Fig; 2 is 9. plan view of the some. Fig. 3 is a. longitudinal vertical sectional view of the cylinder, piston and. drill carry- 'ing rod. Fig. 4 1s a plan viewofthe piston partly in section in a line at a right angle to the line onwhich the section of Fig. 3 is taken Fig.5 i sen end view of the drill. Fig? 6' is ahorizontal sectional view of the spslrliing device. Fig. 7 is a side elevation Fig. 8 is. across-section of a. mechanism on line X X of Fi .3.v

An adjusting screw 2 with a crank Is serves elong the sad die and flanges 4i on the lower side of the c g5 run in guide ways inthe inner o I e saddle as shown in F 5. The cylinder 6 has at its forward end 8. flange 7 which is bolted to a corresponding fi&"""ge 8' on the casing while at the other heed 9 of the cylinder-is the explosion er 10.- The cylinder is shown prosary openings Specification of Letters Patent.

other used.

The cylinder head 9 carries the gssolene or oil tank 11 and the cerburet-erlZ and the eX- 1 water, but it is obvious that any .plosive vspor enters the chamber 10 through the pipe 13 and valve 14 when the latter is cctuetec'l by the mechanism which will be described lster. A velve15 in the heed9 is opened by suitable mechanism, which I will j hereinafter describegto relieve thecylincler and explosive ch'ember of the spent products' fifi of the explosion. Thesevdlves l4 and 15 are 7 identical in construction, each having a stem 16 threaded at its outer end to receive e not 17, and the stem playing in a vclv cesing 18. The nut 17-secures upon the s em a, cup '19. containing 9; spiral spring 20 which er compression ing in the head 91h is secured thereto by .75 means of the bolts 21 passing through flanges 22 on the valve casing and into the heed. In Fig 2 the valves are shown their places in. the head 9 and closed bythe action of the springs 20 but it is evident that e pressure on theends of the stems would open the valves. The cylinder is also provided with e sperker 23 and a. lubricating oil cup 24.

' The casing 5 which incloses the crank and crank shaft together with part of the iston is mode in two sections which when Olted' together is of a shape conforming with these Sorts and is suitably rovided with 'cylin ricsl ends 25 and 26 aving webs to strengthen the whole. Openings in 9.0 themiddle of each side form the bearin s for the crank shaft 27 whichcarries st eec end; fly wheels 28 and has its crank arms',29-interposed between these wheels and within the cssingsnd united bvthe-pin' 39.

The piston is more 0 early shownin Figs. end i where it will be seen to be composed of a. cylindrical 30 having 5. head 31 and provided with annular channels 32 fonthe packing a transverse cylindrical portion 33100 at about its center and a forward extending tube Mend bell shape extension 35 forthe drill carrying rod and itshuiien. The part 30 near its. rear end hes et onsversepin 36 carrying one end of the connecting'rod 37 whose other end cerries'in its'box 38 the crank The part 33 of the piston has slots 40 in itscylindricsl wells for the play of the,

i rotating said drill-carrying rod, and resilient" seasov ing rod having a reduced portion, means for means connectin'g'the reduced portionof the drillcarrying rod and the piston, saidmeans comprising rings, and balls held between said rings andsaid reduced portion of the .drill ro rotating said duced portionggif the drill rod.

3.1 In a rock drill, the combination with an explosion chamber, of a iston, a drill-carrying rod-havin a reduce portion, meansfor rill-carryin rod, and resilient means connecting the dri -carrying rod and the piston, said means consisting of rings having adjacent beveled faces, a yielding device pressing against said devices held between said rings, and rolling rings and bearing upon said reduced portion of the drill-carrying rod.

4. In a rock drill the combination with an explosion cylinder, of a casing connected thereto. a hollow. piston within the cylinder and casin ,a drill carrier, resiliently connect ed with .t e piston, connecting rod and arms within the piston, a crank shaft and flywheels.

5. In a rock drill, the combination with an explosioncylindenof a casingconnected thereto, a hollow piston within the cyLnder and casing, a vdrill carrier resiliently and rotatingly connected with the forward end of the piston,

6. In a rock drill? the combination with an explosion c linder, of a casing connected thereto, a iollow piston operatin in the cylinder and easing, a connecting rod secured within one end of the piston, arcrank shaft rotated thereby, fly-wheels carried by said shaft, a drill carrier adapted to play in the other end. of the piston, yielding means connecting the carrier ,with the piston and rotating means carried by the drill carrier and operated by the piston.

7 In a rock drill, t e combination with an ex losion cylinder ha ing an extension, of a ho low nistzsh operating within the, cylinder and extens cin, a crankshaft, a rod Within and said crank shaft, a drill-carrier operating within one end of the piston and having a reduced portion, spring pressed means retaining the drill-carrier normally by ineans of the reduced portion at a-certainpoint in its end of the pistbn, and rotating means-com the piston, said rod connecting said piston meted with edrill-carrier and operated byfn the piston.

8. In a rock drill, the'combination with an explosion cylinder having a forward exten-' Y sion, of a hollow piston adapted to operate within the cylinder and extension, an enlarged head on the forward end of the piston,

a drill carrier secured within the forward end of the piston and having a reduced portion," rings with o positely inclined sides within? the enlar edead, a spring within the same head and earingagainst one of the rings and ball bearings playing'on the reduced portion} of the drill-carrier and in the space between .3
